whatcha feeding it, looks like shes hungrryy!? you want to chop the top to clone? you should wait until you have about a 3-4 inch clone stem, mind you the top part of the plant are a litttttle more difficult to get her rooted but itll happen with patience. if your trying to get a mom first I would said fim her now, let the branches get to about 4 inches then you can clone and have a nice bush
